Subject: 13.2.3; TeX-LaTeX-Sentinel: a way to stop requiring version line?
Date: Thu, 28 Dec 2023 20:28:25 +0000

I have a few commands in `TeX-command-list' that produce way less output
than typical runs of latex or latexmk. They use texfot
<https://ctan.org/pkg/texfot> to eliminate clutter that requires no
action. Otherwise, they behave in a way where using TeX-run-TeX to run
them and process any errors or warnings that arise would make sense.

Unfortunately, if `TeX-LaTeX-Sentinel' doesn't find any other errors, it
looks for a version line, and if it doesn't find that, it reports
"problems after {(TeX-current-pages)}", and skips reporting warnings or
bad boxes.

My workaround is to insert the text "LaTeX Version" into the script
output to make `TeX-LaTeX-Sentinel' happy. But this is clunky.

It would be best if there were a way to customize the regular expression
that is searched for on successful run of a command. It might be
possible to get rid of this check altogether--it's might be that
checking for a version banner that occurs at the top protects doesn't
protect against many unexpected error conditions--but I assume it's
there for a reason.

I think that the reason why `TeX-LaTeX-sentinel' searches for the
version banner is to check whether there is a working TeX distribution
at all.

The importance of this check is low since `TeX-command' introduced
similar check by `TeX-check-TeX'.

To developers: How about removing this check by the attached patch
(which may be a bit radaical change)?

Thanks for looking at this.  Does your comment above also apply to users
who have set `TeX-check-TeX' to nil?

> To developers: How about removing this check by the attached patch
> (which may be a bit radaical change)?

My suggestion is not to do it now.  Can you think of a sort of advice
around the `TeX-LaTeX-sentinel' function?

OK. As Michael suggested to have customizable regexp, my next proposal
is the attached patch. What do you think about it?

Hi Keita,

sorry for my late response.  If it fixes the issue reported by Michael,
we can install it.  Is it possible to add this new variable to the
manual as well?

TIA.  Best, Arash

OK, here is such a proposal. I think this change is quite safe, so I'll
commit it soon.
